COMPACT SPARE TIRE 
Although  the compact  spare was  fully  inflated  when  your  vehicle  was 
new,  it can  lose  air after  a time. Check  the inflation  pressure  regularly.  It 
should  be 
60 psi  (420  kPa). The compact  spare is made  to go up  to 3,000 - 
miles (5000 km), so you can finish  your  trip  and have  your  full-size  tire i* u 
repaired or replaced where  you  want.  Of course, it’s  best  to replace  your I 
spare with a full-size  tire as soon as  you can.  Your  spare  will last longer 
and  be  in good  shape  in case  you need  it again. 
Your  anti-lock  brake system  warning  light  may  come  on when 
you are 
driving  with  a compact spare.  See “Anti-Lock  Brake System  Warning 
Light”  in the  Index. 
Don’t  use  your  compact  spare  on  some other  vehicle.

TIRES 
We don’t  make  tires. Your  new  vehicle  comes with  high  quality tires  made 
by  a leading  tire  manufacturer.  These  tires  are warranted  by the  tire 
manufacturers  and  their  warranties  are delivered  with 
every new Cadillac. 
If your  spare  tire  is  a different  brand  than  your road tires, you  will  have a 
tire warranty  folder  from  each of these manufacturers.

When to Check Check  your tires  once  a  month  or  more. 
Don't  forget  your compact  spare  tire. It should be  at 
60 psi  (420 kPa). 
How to Check Use  a good quality  pocket-type  gage to check  tire 
pressure.  Simply looking  at  the  tires 
will not tell  you  the pressure, 
especially 
if you  have  radial  tires -- which  may  look properly  inflated even 
if they're underinflated. 
If your tires have  valve  caps, be  sure  to put  them  back on. They  help 
prevent  leaks by keeping  out  dirt and moisture. 
Your  tire  pressures  are: 
Front  and  rear - 30 psi (210 kPa) 
Optional  Limousine  packages: 
Front  and  rear - 35 psi (241 kPa) 
Recommended  tire  size is: 
0 P235/70R15 (Front  and  rear) 
0 T145/80D 16 (Compact  spare) 
0 P235/75R15 XL (Coach  Builder  Option) d

To make your  tires  last  longer, have them inspected and  rotated  at  the

After  the tires  have  been  rotated,  adjust the  front  and rear  inflation 
pressure  as  shown  on the  Tire-Loading  Information label. Make  certain 
that  all wheel  nuts  are  properly tightened.  See  “Wheel  Nut Torque” in the 
Index. 
A CAUTION: 
Rust  or  dirt  on a wheel, or on  the  parts  to  which  it is  fastened, 
can  make  wheel  nuts become  loose  after a time.  The wheel  could 
come 
off and  cause  an accident.  When you change a wheel, 
remove  any rust 
or dirt  from places  where the wheel  attaches  to 
the  vehicle.  In  an emergency,  you  can use 
a cloth or a paper  towel 
to do this;  but be sure  to use a  scraper 
or wire brush  later, if  you 
need  to,  to get  all  the  rust 
or dirt off. (See “Changing a Flat Tire” 
in  the  Index.)

If you ever  replace  your  tires  with those  not  having a TPC Spec  number, 
make  sure  they  are  the  same size, load  range,  speed  rating  and 
construction  type (bias, bias-belted  or  radial) as your  original  tires. 
A CAUTION: 
Mixing tires  could  cause you  to  lose control,  while  driving.  If  you 
mix  tires  of  different  sizes or  types  (radial and bias-belted 
tires),  the  vehicle  may not handle  properly, and you  could  have  a 
crash. 
Be sure  to  use the same  size and type tires on  all wheels. 
It's  all right  to  drive  with  your  compact  spare,  though.  It was

Ungorm Tire  Quality Grading 
The following  information  relates  to  the system  developed  by the  United' 
States  National  Highway  Traffic  Safety Administration  which grades  tires 
I 
by treadwear,  traction  and  temperature  performance.  (This applies only 
to  vehicles  sold in the  United  States.) 
Treadwear 
The treadwear  grade  is a  comparative  rating  based  on  the wear  rate  of 
the  tire  when tested  under  controlled  conditions  on a specified 
government  test  course.  For  example, a  tire  graded 
150 would wear  one 
and  a  half 
(1 1/2) times  as  well  on  the  government  course  as  a  tire  graded 
100. The  relative  performance of tires  depends  upon  the  actual 
conditions 
of their  use, however,  and may  depart  significantly  from  the 
norm  due  to  variations  in  driving habits, service  practices  and  differences 
in  road  characteristics  and  climate. 
Traction -A, B, C ! 
-and concrete. A tire  marked C may  have poor  traction  performance. I I 
The  traction  grades, from highest to lowest  are: A, B, and C. They 
represent  the  tire's ability  to stop  on  wet pavement  as measured  under 
controlled  conditions  on specified  government  test  surfaces 
of asphalt
